Usually it would be on Christmas Eve. Like around 2 hours before midnight. So by the time we get out it is Christmas Day. We did that mostly when I was younger but nowadays no one wants to go that late so we just wait until the next morning or just to to the Christmas church service either the Sunday before or the Sunday after. I miss the feeling of going on Christmas Eve though since they would have a play with the Christmas story. One time I was one of the angels since I was short. At least I wasn't the sheep.
